Abstract:

A series of artemisone derivatives was prepared from dihydroartemisinin through a seven-step conversion, which included the amination of dihydroartemisinin with thiomorpholine, the oxidation of thiomorpholine(2) with hydrogen peroxide, the alkylation of sulfone(3) with the silyl protected 4-iodobutan-1-ol, the desilylation of artemisone derivative(4), the conversion of alcohol(5) to iodide(6), the amination of iodide(6) with piperazine, and the sulfonylation of compound 7 with a wide arrange of sulfonyl chlorides to the desired artemisone derivatives(8). All the new compounds were identified by NMR spectra, IR and HRMS technology. The anti-tumor activities of artemisone derivatives against human hepatoma SMMC-7721 cell lines were evaluated by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide(MTT) method. It was found that these new artemisone-piperazine-sulfonamide derivatives could inhibit the proliferation of the liver cancer cell by inducing apoptosis, and the lowest IC₅₀ value of the treatment for 72 h was 0.09 μmol/mL.
